  • 1. The relief model
  • 2. IndexKinds of relief model
    Fluvial model (rivers)
    Torrential model (torrents)
    Glacier model (glacier)
    Karstic model (subterranean water)
    Litoral model (swell)
    Eolic model (wind)
  • 3. Fluvial model
    Form narrow pass, flood plains and wave-cut platform. This areas are very goods for the farming and the human occupation.
    Form valleys with “V”
    In Spain this kind of erosion is very frequent.
  • 4. Fluvial model
    Narrow pass river Cares (Picos de Europa)
  • 5. Fluvial model
    Flood plains (River Pas and Narcea)
  • 6. Fluvial model
    Wave-cut platform (River Cinca)
  • 7. Fluvial model
    Meanders of a river (Valle en artesa)
  • 8. Fluvial model
    Valley with form “V”
  • 9. Torrential model
    It type of relief model is very erosive and origin beautiful landscapes.
    Origin relieves like canyons and carcavas.
    When are accumulated the erode materials form alluvial fans erosions.
    They aren´t good areas for the population and farming.
  • 10. Torrential model
    Carcavas Tabernas desert (Almería)
  • 11. Torrential model
    Almadenes Canyon (Cieza) Río Lobos Canyon (Soria)
  • 12. Torrential model
    Waterfalls and rapids. They are very frequents in high mountains.
  • 13. Torrential model
    Ravines and narrow pass. The aggressive erosion origin for the water and the materials that the water bring, form the ravines.
  • 14. Glacier model
    This kind of model is origin in high mountains areas, very colds zones.
    The human occupation is very small and this areas normally are touristic.
    The glacier valley has got “U” form and it has got quite population.
    Form glacier cirques and other forms.
  • 15. Glacier model
    Glacier cirques. Origin for the accumulation of ice.
  • 16. Glacier model
    “U” form valley origin form the weight of the block of ice.
  • 17. Glacier model
    Glacier erosion.
  • 18. Glacier model
    Kinds of erosion in the glacier model.
    Glacier spite, morren and glacier cirque.
  • 19. Glacier model
  • 20. Glacier model
  • 21. Glacier model
    Glacier lake. Typical in post-glacier landscape
  • 22. Glacier model
    Erosion in rocks. The water infiltrate in the rocks, and when is freeze, this water occupy more, and the rock is broken.
  • 23. Karstic model
    In areas forms for limestone or plaster, the water infiltrate in crack, and it dissolving the rock and form galleries and caverns.
    There are two types:
    - Superficial: origin form the dissolution and the roof of the cavity like dolines.
    - Subterranean.
  • 24. Karstic model
    Galleries and caverns
  • 25. Karstic model
    When the water is infiltrate can produce stalactites and stalagmite for the calcium carbonate dissolved in the water.
  • 26. Karstic model
    Dolines.
  • 27. Littoral model
    The swell is an agent very erosive.
    When the swell is more aggressive form cliffs, capes and ledges.
    When the swell is not very aggressive form beaches, the place where the eroded materials are accumulated.
    When the cliffs are eroded form abrasion platforms.
  • 28. Littoral model
    Cliffs. Platform abrasion.
  • 29. Littoral model
    Cliffs. Platform abrasion.
  • 30. Littoral model
    Formation of cliffs.
  • 31. Littoral model
    When there is a cliff can origin arches.
  • 32. Littoral model
    In the littoral model can origin beaches, tombolos and arrows.
  • 33. Littoral model
    Littoral lakes.
  • 34. Eolic model
    In Spain this model is not very important, but the wind transport the sand accumulated in the beaches, origin coastal dunes.
    Is predominant in deserted zones.
    When the wind carry the sand and the clay form rocky deserts.
    When there are sedimentation of sand, is origin dunes field.
  • 35. Eolic model
    The particles in the wind origin corrosion in rocks so the rocks have got different shapes.
  • 36. Eolic model
    Rocky deserts.
  • 37. Eolic model
    Dunes fields.
  • 38. The end
